This invention relates to new and useful improvements in Scrapers, andparticularly to road or field scrapers.

One object of the invention is to provide e a device of this characterwherein the scoop is .normally held in non-scraping position,

and which is provided with .means whereby the operator may tilt thescoop into digging position, at will.

E Another object is to provide a device of this character which isequipped with means tor permitting the scoop to turn into digging orloading position, and then be released so as to automatically move intol dumping and leveling position.

Another object is to provide means operable to loch the scoop in diggingor loading position, and in dumping position, successively, at the willof the operator.

A further object is to provide a device oi'l this character whichincludes means tor holding the scoop in either digging or duin ingpositions, and which means is operaio e to release the scoop to permitthe saine to i make a complete revolution, on the ground, back intonormal non-digging position, to be en aged by the holding means.

still further object is to provide a device oi this character whereinthe means Figure l is a top plan view or the device.l

Figure 2 is a side elevation of the same, the scoop being in non-diggingposition.

Figure 3 is a sectional view on the line M 3 3 of Figu'rel.

Figure i is a similar sectional view showing the scoop in diggingposition.

. Referring particularly to the accompanying drawings, 10-v represents ascraping scoop, having the pintles 11 in the end walls 65 to which areconnected the arms of the draft frame l2, said frame extending forwardlyin converging relation and carrying, on the forward end, the centrallypivoted vertical rockable member 13. rlhe lower end of the @0 member 13is provided with the means l0 for connecting the same to the draft lugof Connected to the frame l2, and extending transversely of the iront ofthe scraper, is a bar le, and connected to the @5 intermediate portionof said bar, at its rear end, and to the convergent ends of the traineis a forwardly extending brace member i5. Straddling the intermediateportion ofi the brace l5, and pivoted thereto, at l5', is the Tovertically extending lever 16. in the intermediate portion oi this leverlo there is formed a longitudinal slot 17. Pivotaily connected, at 18",to the upper end oi the roclrahle member 13, and extending rearward'lyin straddling relation to the lever 16, are thebars i8, a pin 19 beingdisposed through said bars and said slot i7, tor the purpose ofpermitting forward and rearward sliding movement o said bars 18, upon@it rocking the said lever. These hars 18 are capable of adjustability,as to their lengths, hy means of the a ertures 19', and holte 20.Secured to the bac of the scoop 10, and extending vertically in parallelrelation, are the guldes 21, the upper ends of said guides being curvedforwardly. over, and .above the upper edge of the back of the scoop.Extending between these curved ends of the guides, is a transverse pinor holt 22, to which reference will be made later herein. Similarlydisposed between the other ends of the guides is a pin 23. Each of thesepins4 is removably held in the openings of the guides by means of thecotter pins 24:. 95 It will be noted that the ends of the guides areprovided with the series of openings 25, for interchangeable receptionof the pms or bolts 22 and 23. The rear ends ot the bars 18 extend overthe upper pin 22, and pivot lo@ ally mounted between said ends of thebars, onA the pivot pin 26", carried thereon, is a j gravity pawl 26,arranged to engage with pawl.

said pin, whereby to hold the scoop against any tendency toward rearwardtilting ac-` tion. Disposed between the bars 181is a lever 27 the rearend of which is provided with'a pair of rearwardly extending arms 27',which straddle the pawl 26, and are pivotally supported on the pivot ofsaid The rear. end of the lever 27 is turned downwardly to form the nose26', which engages with the forward side of the pin 22. The forwardend-of the lever 27 is provided with an opening 28 in which may besecured any suitable means wherebythe driver may lift the lever, fromhis seat on the tractor. The upper end of the lever 16 is provided withan opening in which is se- 5. level the material dumpe 6 cured one endof a flexible member, such :as the-rope 29, which rope is grasped by thedriver of the tractor, for the purpose of 4pulling the lever forwardly,wherebjT to cause the pawl 26 to impart an initial tilt of the scoop sothat the ed e thereof will engage with the ground. T e ends of the scoopare provided with the shoes or runners 30, on which the scoop is adaptedto roll, or to drag, according to the position of the scoop, whether ornot .the pawl 26, and lever 27 are engaged with either of the pins orbolts 22-23. I

It will be noted that the normal forward pull of the tractor, on theclevis, or connection with the forward ends of the bars 18, that is thelower end of the rocker 13, ur es the bars 18 rearwardly, with theresult t at Athe rear end of the lever 27 presses against the upper pin22, causing the scoop to tilt rearwardly, and elevate its foredge abovethe ground, whereby to prevent digging action thereof. When the operatordesires to place the scoop in digging and loadin position, he pullsl therope 29, causing the ever 16 to move forward, drawing the bars 18 withit, and thereby engaging the pawl 26 with the pin 22, which rocks thescoop forwardly to engage its digging edgein the ground.

When it is desired to dump the loaded scoop, the operator lifts theforward end of the lever 27, yso as to elevate thenose 26 vabove the pin22, when the normal contact of the scoop with the ground, will cause thescoop j to roll forwardly, as the scoop is drawn over the ground, the in22 passing freely beneath said nose. Ii) the operator releases the lever27, immediately after it has become. disengaged from the pin 22, thesaid lever will engage with the pin 23, when the scoop has rolled intothat position, thus causing the scoopto remain in such position andpermitting the digging edge to properly from the scoop. After the scoopis empty, the operator again raises thel lever 27 whereby the scooprolls 'or turns on the ground until the pin 22 is again engaged betweenthe pawl 26, andthe adjacent end ofthe lever 27 whereby the scoop isrestored to its non-diggingdposltion. In Figure 6, there is shown a moification of the bars and levers, wherein the bars l18".

er end of the rocker 13 and to the lower end of the lever 16', thislatter lever being pivotally supported on the frame 12. The action ofthis form of the invention has the same results as that of the firstform. The releasing lever is shown at 27.

What is claimed is:

1. In a` scraping and leveling device, the

combination with a rotary scoop having a stop pin, a movable arm havingan end adjacent said stop pin and having a detent engaging with one sideof said stop pin for preventing y retrograde rotationl of said scoop,and a lever havin one end pivotally mounted on said arm adjacent saiddetent and having a nose on saidpivoted end engaging the other side ofsaid stop pin.

2. rIn a scraping and leveling device, the

combination with a rotary scoop having a stop pin, an arm having saidstop pin, ,a pawl pivotally carried by said arm engaging one side ofsaid stop pin to prevent retrograde rotation of the scoop, aleverextending longitudinally of said arm and having an end curved downwardlyto provide a nose engaged with the other side an end adj acent.

of said stop pin and an arm carried by said v lever extending beyondsaid end and pivotally mounted on said first-named arm coincidentallywith the said pawl, whereby said I lever may be swung on its pivot todisengage its nose frolnsaid stop pin so that said scoop may rotateforwardly.

3. In a scraping and leveling device, the combination with a rotaryscoop having astopypin,a movable arm havin an end adjacent said pin andhaving a etent engaging with one side of said pin for preventingretrograde rotation of said scoop and la lever extending longitudinallyof said arm and having one end (pivotally connected to said arm adjacentsaid detent, said lever having a downwardly curved portion forminga noseenga ed with the-other side of said stop pin an movable to disenga esaidnose from said pin to permit forwar rotationl of the scoop. i

4.' In a scraplng and'leveling device, the combination with a rotaryscoop having `a stop pin, a movable arm havin an end adjacent said pinand havin a etent engaging with onevside of said pm for preventingretrograde rotation of said scoop, and a manually oV erable leverextending longitudinally o said arm and having a downwardly curvedportion formin a nose engaged with the other side of sai stop pin toprevent forward rotation of said scoop, said lever beingvpivotallconnected beyond said nose toasaid arm a jacent said detent.
